Summary

Using wearable devices in the home setting allows continuous remote monitoring and feedback for intense self-directed training, an effective alternative to in-person rehabilitation. Emerging literature demonstrated that wearable devices are promising tools to enhance and deliver home-based upper limb training in stroke survivors. Nevertheless, previous reviews (Wang et al., 2017; Rodgers et al., 2019) highlighted a paucity of high-quality evidence concerning the clinical application of wearable devices in home-based rehabilitation. This study examines the effectiveness of the enhanced version of the wearable device as a home-based upper limb rehabilitation intervention to improve the hemiplegic upper limb motor function of persons with stroke. The study seeks to address the research question: 'Is wearable device intervention in the home more effective in promoting arm recovery in stroke survivors than conventional therapy with a sham device after treatment and follow-up?' We hypothesize that the multimodal feedback system and improved features from the wearable device will provide a more effective and sustainable treatment option than conventional therapy with a sham device to promote the motor recovery of the hemiplegic UL function in persons with stroke. A parallel single-blinded randomized controlled trial will be conducted in Hong Kong hospital outpatient and/or community stroke service settings. There will be two study groups: (1) a wearable device group and (2) a sham group. Forty participants will be randomly allocated into any of the two study groups (1) the experimental (wearable device) group and (2) the sham group (use the pictorial handout and sham device) using a computer-generated random number sequence to conceal the allocation. Participants in the experimental group will undergo a 4-week wearable device treatment and participants in the sham group will receive a sham device and complete a 4-week conventional training. Upper limb motor outcome measures will be evaluated at the following intervals: baseline, post-treatment at 4-week, and follow-up at 8-week by blinded assessors. The results of this study will show the possible efficacy of the wristwatch device in promoting motor recovery of the hemiplegic upper limb in stroke survivors and pave the way for an alternative stroke therapy that uses novel wearable technology in the home setting.

Interventions

Type	Name	Description
DEVICE	Wearable device -'Smart Reminder'	The wearable device, a wristwatch, has a Bluetooth function to link to mobile devices for the participants to view the prescribed videos and engage in telerehabilitation. It has sensors to monitor arm movements and provides multiple feedbacks (auditory, visual and tactile). Participants were instructed to practice the prescribed exercises -tailored according to the severity of UL paresis for the recommended therapy dose. The device recorded the angles of arm movement and the number of repetitions completed and data collected is uploaded to an encrypted cloud server for remote monitoring. Weekly, the participants will receive a 45-minute consultation session to review their progress and modify prescribed exercises based on the wearable device data.
DEVICE	Sham device	The sham device is also a wristwatch, which consists of an accelerometer, a gyroscope sensor, and a rechargeable battery that supports up to 72 hours of continuous use. The device will monitor the participant's arm activity, but it will not emit any reminders or be connected to a telerehabilitation system. The participants were instructed to perform the exercises from the pictorial handout for the recommended therapy dose and received a weekly therapy consultation as well.
